Step-by-step explanation:
Given data is is predicate that
then
. where
are rational numbers.
a)
when
Here that is
satisfied. Then
this is wrong. since
That is Thus
is false.
b)
Assume .
That is
Here that is
this condition is satisfied.
Then
this is not true. since
.
This is similar to the truth value of part (a).
Since in both satisfied and
for both the points.
c)
if that is
and
Here this satisfies the condition
.
Then
This also satisfies the condition
.
Hence exists and it is true.
d)
Assume
Here satisfies the condition
Then
satisfies the condition
.
Thus, point exists and it is true. This satisfies the same values as in part (c)
